We have developed a convenient method of measuring the temporal chirp structure of white-light continuum pulses used in femtosecond time resolved absorption spectroscopy. This method, based on the nonresonant optical Kerr effect, is superior in many respects to the existing one that uses the sum or difference frequency generation by a nonlinear crystal.
